FCS has such a wide range of fins. Where do I start?

The best place to start is to identify the correct size fin to suit your weight. All FCS fins are categorised into different sizes (XS, S, M, L and XL) with each size representing a specific weight range. For example; if you weigh 70kg a medium (M) size fin will work the best.


I know what size fin I want, what’s next?

Once you have identified your weight range and fin size, you can then choose between a variety of different templates, materials and foils depending on the performance you require. Use the performance ratings as a guide to individual fin performance and customise your quiver.


What are performance ratings?

All FCS thruster and quad fins come with a fin rating. These ratings provide the drive, pivot and hold characteristics of each individual fin set. These rating can be used as a reference when choosing a fin for specific performance requirements. For example; if you want a large fin with plenty of drive, choose a (L) size fin with a drive rating of 4 or 5. If you want a fin that turns in a tight radius then choose a fin with a low pivot rating of 1 or 2.


Where can I get more information so I can make an informed choice when choosing a fin?

The information contained in the TECHNOLOGY tab on this website clearly explains all the elements that have an influence on fin performance.


Can I test drive a fin?

Once you have identified a fin that suits your weight you can test that particular fin for free at one of our many FCS Test Drive Centers. These Test Drive Centers can be found at most leading surf retailers and are the ideal way to try before you buy. Because FCS has such an extensive range of fins available, we encourage you to test fins prior to upgrading to a different material or template.


Do fins really make a difference?

Yes, fins make a huge difference. Fins provide direction, acceleration and allow you to apply power into your turns without loosing control. Different fin sizes, templates and foils can also change the way a surfboard will perform.


What’s the difference between each of the fin materials?

No one material is better than another. While some materials are technologically more advanced, the choice is ultimately up to the consumer. Different fin materials provide a variety of performance options by applying different construction methods, foils, and flex patterns. For more detailed information on each material please refer to the TECHNOLOGY tab in the menu bar.


Ultra-Light Epoxy: The lightest fin material available on the market utilizing injection molded epoxy construction to ensure foil accuracy and precise tip response. UL offers an extremely high strength-to-weight ratio.


Performance Core: Delivers the feeling of a traditional glass fin with the added performance of reduced weight. Injection molded construction offers responsive tip flex, a stiff base, and an impressive aesthetic.


Composite Core: A composite insert is used with the injection molding process to produce a fin with engineered tip flex. Delivers the feeling of a traditional fiberglass fin with a stiff base and a dynamic tip flex.


Performance Glass: Computer cut panel fiberglass fin delivering a flex pattern identical to traditional fixed fins. The ideal fin for surfers making the transition to the convenience, accuracy and performance of FCS.


Glass Flex: Composite fin designed to replicate the flex and memory properties of laminated fiberglass. These versatile fins deliver remarkable speed and response through superior flex memory and a stiff base.


Is FCS really the strongest fin system on the market?

Yes, in all of our testing FCS has proven to be the strongest fin system on the market. This is due to the patented H-Pattern installation process which anchors the plugs to the deck and bottom surfaces of the board. Along with the stringer, the fiberglass on the deck and bottom of the board are the only areas with any structural strength. Having a high strength anchorage system allows the fins to snap off at the tabs without damaging the board or the plugs during severe side impact situations. To learn more about the FCS X-2 system go to the TECHNOLOGY tab on this website.


What is the difference between X-2 & Fusion?

The FCS X-2 plug is primarily used in traditional PU/Polyurethane construction and is designed to be installed after the board is glassed. FCS Fusion is used primarily in EPS/Epoxy construction and is designed to be installed before the glassing process, otherwise known as pre-glass.


Don’t most of the pros ride fixed fins anyway?

No they don’t, currently well over half the World Tour (men and women) choose to ride FCS.  To date, 14 ASP World Titles have been won on the FCS system. No surfer has won a world title on any other fin system.


Is it possible to over tighten screws?

Yes, you can over tighten the screws. Over tightening will cause damage to the fin tabs and can also cause the thread of the plug to burr. This happens when the screw protrudes too far into the tab and loses connection with the plug thread. Use this method: Tighten the fin screw until you feel a moderate amount of resistance and then give the screw another half turn, this will secure the fin in place. Periodically check that the screws are still secure and tight.


How do you remove a stripped screw from an FCS plug?

Use the ezi-out tool head that comes with our FCS ratchet tool. The ezi-out tool head has a slightly bigger diameter then the regular FCS key. This tool will fit snuggly in the stripped screw. Slowly and carefully remove the stripped screw. 


I snapped a fin out, how do I remove the fin tabs from the plugs?

The fin tabs are manufactured to fit snuggly in the plugs so they can be quite difficult to remove when a fin snaps out of the board. Ensure you have loosened the screws and use a small screwdriver or pointed tool to leverage the end of the tab out of the plug. Alternate between the two ends so the tab is extracted bit by bit until it is completely removed.


Why do my fins sometimes hum?

Fins hum because of unstable water flow at the trailing edge of the fin. This generates vortices or turbulence which results in a fin that hums. To fix it, use 100-150 grit sand paper to make a bevel on each side of the trailing edge. The idea is to reduce the likelihood of water separating by thinning out the trailing edge. We recommend you sand the fin a little then surf the board again, if it still hums sand it some more. For safety reasons we intentionally manufacture our fins with a rounded trailing edge. On rare occasions this causes the fins to sing or hum.


How do I make a board stiffer?

It’s possible to make a board stiffer by selecting a slightly larger fin template that you would normally ride. Choosing a bigger back fin will also make a board significantly stiffer.


How do I make a board looser?

It’s possible to make a board looser by selecting a slightly smaller fin template that you would normally ride. Choosing a smaller back fin will also make a board significantly looser.
